How many sites per tooth are probed in a full periodontal examination?

• A. Four sites per tooth are probed.
• B. Six sites per tooth are probed.
• C. Eight sites per tooth are probed.
• D. Twelve sites per tooth are probed.

Answer: (B)

Six sites per tooth are probed during a full periodontal examination. This approach recognizes that pocket depth and attachment loss can vary around a tooth, so checking multiple surfaces gives a complete picture of periodontal health. The standard six sites are mesio-buccal, mid-buccal, disto-buccal, mesio-lingual, mid-lingual, and disto-lingual. Probing only a few surfaces could miss a deeper pocket on an unexamined side, while probing more than six surfaces adds measurement time without providing essential additional information for routine screening. This balanced approach ensures localized disease is detected and the overall periodontal status is accurately assessed.
